This invention:relatesl generally togas meters used to recordtheam0ll1ltof gas used or consumed, the invention haying more particular, referenceY to a` novel, type ofV improvement forv gas lmeters embodying a mea-ns. oflpreventing the useof gaSl,.Ji1.r.0.1lgl1.v agas. meter4 without recording, the. amount of gas used.

The invention has.y for anl ,objectif the 'P1792' vision of an improved device of theclass` d-eecribed, ofi simple, novel construction, cheaply manufactured. and effective..

Forufnrther comprehension of the inven-v tion, and .offth'e objects and advantagesthere.-l of, reference willbe had toI thef following. descriptiony and accompanying drawings, andi to the appended claims in whichfthe various noyel: features of; the inventOn., are more .particularlylset forth. l j

The inlet 13 is connected to the gas meter 10, and is also connected by means of the coupling 14 to the pipe 15, which is connected to a gas main or any suitable source of gas supply, not illustrated in the accompanying drawings. The'outlet 16 is connected to the gas meter 10, and is also connected bymeans of the coupling 17 to the pipe 18, which is connected to any desired gas jet or plurality of gas jets such as commonly used for light-ing, heating, cooking or wherever gas is used.

It is common knowledge that gasmeters are constructed with certain apparatus to record the amount of gas flowing therethrough, and that this apparatus includes certain valves. If these valves are forced open by means foreign to the meter, an escape for-the gas directly from the inlet to the outlet is afforded, without the proper registering of the meter. It is also common knowledge that certa-ill means may Y 82 which.' extendsl diagonally stilista memberz 3.0: As.. shown. in: iigiii'e. L3.,

By disconnacting` thezoutlet 16, detachthe-.cembre 17, the instrument 25, C011- Sistingef .an elongated flexiblemember, wir@ O11 the' like, having abent-exiremiiy-Q,111er. bev inserted in. the Outlet167.504 that ihebent exneliiirl 2.6v Will Pass through the @Per rhenotched 'extremity 0i: the iiieni- Y bers 30; islocatedgn Close proximity-110 .the Outletpassage. 24:., andY tliefs'ide. PQition Of Said tubular .member is;` sighted ,and diseased or. lben-ti11nva1rl-;1y between the. slots "Oils iep.

.o f: the. outlet openingai termine across.deelnemen passeggeri-attrib ar .ls baiile is narrower than the passage in the tubular member 30 and thus provides sufficient space for the passage of gas, but

'prevents the insertion of a.` wire member for thepurpose disclosed above. 'Thelower end section 31 of the tubular member is adapted to `recline adjacent the inner surface of the tube 16. A projection 33 is providedv on the lower Vextremity of the baiiie 32 and is disposed substantially at right angles to the plane of the baille member.

rally This projection is thus directed to direct inserted wires to a point below the outlet opening 24, and is adapted thus, to pre-v vent insertion of the wire into the outletv opening 24 through the space between the extremity of the balile 30 and the tubular member.

The collar 34, washer or the like, removably attached to the outlet 16, by threads or` the like, is positioned inside the outlet 16 above the tubular member, and has removably attaChed thereto, a screw 35, ex-

tending therefrom through an elongated slot 36 in the side of the gas meter 10. A cover plate 37 is secured to the inside of the meter and over the slotV 36 so as to prevent the leakage of gasthrough the slot, The above described construction being such as will prevent the removal of the tubular member 30, when the coupling 17 is detached, and

.which will also permit the tubular member 17 to be lowered as may be desired, which will obviously increase the effectiveness and eiiciency of my improved device.

The device presents a novel feature in i that it may be readily inserted in any old vis installed.

Vhile I have above described the preferred form, construction and arrangement 'of' the severalelements employed, it will be understood' that the device is, nevertheless, susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

- Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as followsz' l. In a device ofthe class described, the combination with a gas meter having a side gas outlet opening into a gas outlet connection, yof a tubular member having spaced slots therein, at the bottom thereof, `and adapted to be insertedin the said outlet connection, the side portion of said tubular i ymember'between said slots being disposed inwardly and extended substantially across the passage therein, and positioned in front of the said side outlet for preventing the insertion of a wire into the said outlet.

2. In a device of the class described, the combination with a gas meter having a side gas outlet opening into a gas outlet connection, of a tubular member having spaced slots therein, at the bottom thereof, and4 adapted to be inserted in the said outlet connection, the side portion of said tubular member between said slots being disposed inwardly and extended substantially across the passage therein, and positioned in front of the said side outlet for preventing the insertion of a wire into the said outlet, and means controlled from the inside of the meter for preventing the removal of the tubular member from the outlet passage ofthe meter.

3. In a device of the class described, the combination with a gas meter having a side gas outlet opening into a gas outlet connection, of a tubular member having spaced slots therein, at the bottom thereof, and adapted to be inserted in the said outlet connection, the side portionof said tubular member between said slots being disposed inwardly and extended substantially across the passage therein, and positioned in front of the said side outlet for preventing the insertion of a wire into the said outlet, a flange projecting from and at right angles to the said inwardly disposedside portion directed to direct wires inserted into the tubular member to a point below theY said side gasoutlet opening, and means controlled from the inside of the meter for preventing the removal .of the tubular member from the outlet kpassage of themeter.r

In testimony whereof I have affixed my signature.
